Call support system, call support method, and recording medium

Abstract

A call support system includes: a speech transmission mode switch unit that switches between a speech transmission permission mode that permits execution of call source speech transmission processing for speech of a user by a call control unit and a speech transmission prohibition mode that prohibits execution of the call source speech transmission processing for the speech of the user by the call control unit; and a light emitting part state control unit that puts a light emitting part, provided in a mobile body to be visible to the user, in a first visible state when the speech transmission permission mode is active, and puts the light emitting part in a second visible state different from the first visible state when the speech transmission prohibition mode is active.

What is claimed is: 
     
         1 . A call support system, comprising:
 a call control unit that executes call source speech transmission processing for transmitting call source speech information, corresponding to speech of a user of a mobile body that is input into a microphone used in the mobile body, to a call destination communication terminal used by a call partner;   a speech transmission mode switch unit that switches between a speech transmission permission mode that permits execution of the call source speech transmission processing for the speech of the user by the call control unit and a speech transmission prohibition mode that prohibits execution of the call source speech transmission processing for the speech of the user by the call control unit; and   a light emitting part state control unit that puts a light emitting part, provided in the mobile body to be visible to the user, in a first visible state when the speech transmission permission mode is active, and puts the light emitting part in a second visible state, different from the first visible state, when the speech transmission prohibition mode is active.   
     
     
         2 . The call support system according to  claim 1 , wherein
 the light emitting part state control unit switches the light emitting part between the first visible state and the second visible state by changing at least one of light emission color, illuminance, lighting and flashing, and a flashing pattern of the light emitting part.   
     
     
         3 . The call support system according to  claim 1 , wherein
 the call control unit executes call destination speech reception processing for receiving call destination speech information corresponding to speech of the call partner that is transmitted from the call destination communication terminal to output voice corresponding to the call destination speech information received by the call destination speech reception processing from the speaker used in the mobile body, and   the light emitting part state control unit puts the light emitting part in a third visible state that is different from the first visible state and the second visible state when the voice corresponding to the call destination speech information is output from the speaker by execution of the call destination speech reception processing by the call control unit.   
     
     
         4 . The call support system according to  claim 1 , wherein
 the light emitting part includes a first light emitting part and a second light emitting part,   the call control unit executes call destination speech reception processing for receiving call destination speech information, corresponding to speech of a plurality of call partners transmitted from a plurality of call destination communication terminals while identifying the respective call partners, and outputs voice corresponding to the call destination speech information received by the call destination speech reception processing from a speaker used in the mobile body, and   the light emitting part state control unit puts the first light emitting part in the first visible state or the second visible state, and when the voice corresponding to the call destination speech information is output from the speaker by execution of the call destination speech reception processing by the call control unit, the light emitting part state control unit puts the second light emitting part in a visible state set for the call partner corresponding to the voice output from the speaker, out of visible states independently set for the respective call partners.   
     
     
         5 . The call support system according to  claim 1 , wherein
 the light emitting part is also used to notify a setting status of equipment provided in the mobile body, and   the first visible state and the second visible state are set to visible states different from the visible state when the setting status of the equipment is notified.   
     
     
         6 . The call support system according to  claim 1 , wherein
 the light emitting part includes a first light emitting part and a second light emitting part, and   the light emitting part state control unit puts the first light emitting part in the first visible state or the second visible state, and puts the second light emitting part in a visible state that notifies a setting state of equipment provided in the mobile body.   
     
     
         7 . The call support system according to  claim 1 , wherein
 the microphone collects speech of the user who is seated on a driver seat provided in the mobile body, and   the light emitting part is provided in an interior part in a vicinity of the driver seat of the mobile body.   
     
     
         8 . The call support system according to  claim 1 , wherein
 the light emitting part is provided individually for each of a plurality of seats provided in the mobile body,   the microphone is individually used by each user of the plurality of seats,   the call control unit executes the call source speech transmission processing for each of the plurality of users,   the speech transmission mode switch unit switches between the speech transmission permission mode and the speech transmission prohibition mode for each of the plurality of users, and   the light emitting part state control unit puts the light emitting parts provided for the seats, used by the users who participate in an identical electronic meeting, out of the plurality of users, in the first visible state or the second visible state in response to switching between the speech transmission permission mode and the speech transmission prohibition mode by the speech transmission mode switch unit.   
     
     
         9 . A call support method executed by a computer, comprising:
 a call control step of executing call source speech transmission processing for transmitting call source speech information, corresponding to speech of a user of a mobile body that is input into a microphone used in the mobile body, to a call destination communication terminal used by a call partner;   a speech transmission mode switch step of switching between a speech transmission permission mode that permits execution of the call source speech transmission processing for the speech of the user in the call control step and a speech transmission prohibition mode that prohibits execution of the call source speech transmission processing for the speech of the user in the call control step; and   a light emitting part state control step of putting a light emitting part, provided in the mobile body to be visible to the user, in a first visible state when the speech transmission permission mode is active, and putting the light emitting part in a second visible state, different from the first visible state, when the speech transmission prohibition mode is active.   
     
     
         10 . A non-transitory recording medium storing a program that causes a computer to function as:
 a call control unit that executes call source speech transmission processing for transmitting call source speech information, corresponding to speech of a user of a mobile body that is input into a microphone used in the mobile body, to a call destination communication terminal used by a call partner;   a speech transmission mode switch unit that switches between a speech transmission permission mode that permits execution of the call source speech transmission processing for the speech of the user by the call control unit and a speech transmission prohibition mode that prohibits execution of the call source speech transmission processing for the speech of the user by the call control unit; and   a light emitting part state control unit that puts a light emitting part, provided in the mobile body to be visible to the user, in a first visible state when the speech transmission permission mode is active, and puts the light emitting part in a second visible state, different from the first visible state, when the speech transmission prohibition mode is active.
